Abstract

Sistemul, conform inventiei, are toate circuitele de supraveghere cu iesirea conectata pe una sau mai multe linii comune de alarma, avînd sarcina de a conduce plusul sursei de alimentare pe aceasta linie, atunci cînd starea logica a circuitelor supravegheate de ele se modifica prin însusi elementul optic de semnalizare. Aceasta situatie este sesizata de circuitul de amorsare a liniei pe care a aparut plusul sursei, care, cu o întîrziere mai mare sau mai mica, amorseaza tiristorul alarmei; cît timp alarma functioneaza, este alimentat si un circuit formator de impulsuri de 1-2 Hz, care, prin intermediul unui tranzistor de putere a unor diode de separare va "pune la masa" aceste linii, provocînd aprinderea cu intermitenta a diodei electroluminescente a circuitului care a generat starea de alarma si numai a lui.According to the invention, the system has all the output supervision circuits connected to one or more common alarm lines, having the task of driving the addition of the power supply on this line when the logical state of the circuits monitored by them changes by itself optical signaling. This situation is perceived by the line-starting circuit on which the plus of the source appeared, which, with a greater or lesser delay, primes the thyristor of the alarm; As long as the alarm is working, a pulse train of 1-2 Hz is also fed, which, by means of a power transistor of some separation diodes, will "put these lines on the table", causing the intermittent ignition of the electroluminescent diode of the circuit which generated the alarm and only his condition.
